A teacher dropped four objects into a cup of water. The diagram shows where the objects settled. Which statement correctly describes the relative density of the objects?

• The ball is more dense than the ring.

• The ring is less dense than the cube.

• The ball is less dense than the gem.

• The cube is more dense than the ring.

Students observed the physical properties of four common objects: Aluminum can, Steel paperclip, Glass marble, Sugar cube. Which of these properties cannot be used to classify these four objects into two different groups?

• Solubility

• Magnetism

• Physical state

• Electrical conductivity

Students investigated physical properties of nine different substances. They made a table to show how those substances can be grouped. Which column headings should the students use for their table?

(a)  

• Magnetic | Less Dense than Water | Good Electrical
• Good Thermal Conductor | More Dense than Water | N
• Poor Electrical Insulator | Insoluble in Water | S
• Magnetic | Insoluble in Water | Poor Thermal Condu

Steam trains became popular about 200 years ago. They burned coal to produce steam. Then, the steam moved the gears and wheels of the train. Four students each made a table with examples of different forms of energy related to a steam train. Which table is correct?

• Thermal, Water boiling; Electrical, Gears turning

• Electrical, Water boiling; Mechanical, Gears turning

• Mechanical, Water boiling; Thermal, Gears turning

• Thermal, Water boiling; Mechanical, Gears turning

A student built a circuit in which the lights all appear lit. Which two switches can be open and still allow all of the parts to work? Mark only one oval.

• Switches 1 and 4

• Switches 2 and 4

• Switches 1 and 3

• Switches 2 and 3

A working circuit is shown. All five of the lightbulbs in this circuit are lit. Removing which wire would result in exactly three bulbs being lit?

The diagram shows a child viewing a cooler that fell in the water. Why is the cooler’s apparent depth closer to the surface than the cooler’s actual depth?

• Light is reflected off of the water’s surface.

• Light makes the cooler grow in size.

• Light refracts as it passes through a new medium.

• The water blocks the light waves from passing through.

Which processes are not required for sedimentary rock formation?

• Processes 1, 3, 4, and 5

• Processes 2, 5, and 6

• Processes 1, 2, and 4

• Processes 1, 4, 5, and 6

Millions of years ago, giant trees grew in swamps. How did those giant trees eventually form coal?

• The trees melted as they were heated on top of layers of sediments over millions of years.

• The trees died, were buried by sediment and rock, and underwent heat and pressure over millions of years.

• The trees died and were buried and compacted under layers of sediment until they became lava.

• The trees burned during wildfires over millions of years.

Which statement correctly describes how a landform is formed?

• A sand dune is formed by a glacier weathering rock and eroding sediments.

• A canyon is formed by the deposition of sediments at the mouth of a river.

• A V-shaped valley is formed by wind depositing sediments near a mountain.

• A wide valley is formed by a glacier weathering rock and eroding sediments.
